When the first Kublai series chassis was introduced in 2007, it had
innovative storage design that was ahead of its time. For the Kublai
KL04, SilverStone engineers again looked to raise the bar with a
design that can accommodate four 5.25” drive bays, nine 3.5” hard
drives, and up to six 2.5” SSDs. This astonishing amount of storage
capacity for a mid-tower chassis is unprecedented and comes with no
compromise to compatibility. Expansion cards or graphics cards up to
17 inches long can be installed without the need to remove hard drive
cage and even with all hard drive bays filled, cards up to 12.8 inches
can still be used. To cope with densely packed hard drive bays,
repeated thermal tests and revisions were made to come up with an
airflow layout that is capable of handling all hard drives installed
without negatively affecting the rest of the system. The right front
positioning of the intake fans also helps to divert noise from leaking
out directly to the front of the chassis. For 2.5” SSD or HDD
mountings, the KL04 has specially designed cages that can be mounted
in two locations depending on user needs. If you are looking for a
chassis with server-like room for expansion but only limited footprint
for a mid-tower, the KL04 is the choice.

*1 – If bottom fan or 2.5” SSD is installed, the maximum
depth for PSU is 180mm (or 160mm with extra cabling room), otherwise there
are no depth limitations.
*2 – If hard drive is installed in front of the cards, the length
limitation is 12.8 inches.
